http://rapidshare.com/fil...ENABLED_radioROM.rar.html
To flash this GPS enabled radio rom your Trinity should have bootloader SPL-1.04 or early version
The bootloader is invoked by pressing down both the POWER button and SIDE Camera together and using the stylus at the same time to press the RESET button at the bottom.
Upgrade instructions
1. Extract the contents of the compressed file you've just downloaded
2. Run MaUpgradeUt_noID.exe
3. The Trinity screen will turn white and show "Upgrade Radio Stack Please wait........."
4. If you get an error, do not disconnect the device, run MaUpgradeUt_noID.exe again.
5. The upgrading process will start and MaUpgradeUt_noID.exe will end up saying "ERROR 114: Upgrade Error", but the radio ROM will be flashed anyway if your bootloader version is SPL-1.04, don't worry about that error!
6. Soft reset with stylus (Device will not be hard reset and no data will be lost)
